Did “Invasions” Occur in the Fossil Record?
A panel of evolutionary biologists during Ithaca Darwin Days reflects on what we can learn about species invasions from the fossil record.Are human-facilitated invasions today the same kinds of events as Earth-facilitated changes in species distributions in the distant past? Are all species invasions “destructive”? Does invasion shut down speciation? Do we really know what the rate of invasion was in the past? In most instances, we simply don’t know.

Taking a Micro-look at Coral Relationships
Corals grow in shapes specific to their surroundings, but this plasticity often masks evolutionary relationships. One must look closer...Sahale Casebolt, a graduate student at Virginia Tech, is comparing micro-features of fossil and modern corals with their DNA sequences to reveal evolutionary relationships.

Snagging a Date 125 Million Years Ago: the Avian Way
Sexual dimorphism, an essential piece of many species’ survival, is the difference in morphological appearance between males and females of the same species. Think Lion King: Simba’s father sported a big bushy orange mane, whereas his mother, also a lion, had no showy neck fur to speak of.

The Search for the Origin of Life
Recent scientific efforts are bringing us closer to an understanding of the earliest life on Earth, and to the fielding of a theory that explains the dawn of our earliest ancestor.The cases of the earliest discovered evidences for life on Earth, if biological in origin, constrain the timing for the emergence of life to sometime before 3.4 billion years ago.
